Abstract
A survey is given of the nuclear magnetic resonance (NMR) experiments in th e manganese perovskites of the form RE(1-x)A(x)MnO(3) and REMnO3+delta (RE = rare earth, A = Ca, Sr, Pa). The Mn-55, La-139 and Sr-87 spin-echo spectr a in the frequency range 5-650 MHz are discussed and the microscopic inform ation on the Mn valence states and the nature of magnetic interactions is a nalysed as a function of the hole doping.
